我們首先要先開機后開屏，先關機然后再先關屏，假如我們先關了計算機而不先關了led屏幕的話，整個屏幕就會出現(xiàn)高亮點**終導致燒毀燈管的危險，燒毀燈管的后果是非常嚴重的。我們不能不斷的進行開關機，開關貧民的時間間隔一定要大于五分鐘，除此之外，我們要避免全白屏屏幕狀態(tài)下開屏，因此這時系統(tǒng)的沖擊電流是比較大的，如果環(huán)境溫度過高或者是散熱條件不好時，這時我們就不要長時間開屏效果不好，如果我們的LED屏經(jīng)常會出現(xiàn)電源開關跳閘的現(xiàn)象，此時我們要檢查屏體進行電源開關的更換，確保正常使用，定期檢查掛接處的牢固情況，如果發(fā)生松動現(xiàn)象要重新加固或者更新吊件。 </p> <p> 二、 LED顯示屏控制系統(tǒng)部分更改、變動注意事項 </p> <p> 1.計算機、控制部分的電源零線和火線不能反過來接，上海工業(yè)安燈看板什么價格，我們應該按照嚴格的位置來接插。如外設、連接完畢之后，我們應該用測試機測試一下是否帶電。 </p> <p> 2.移動計算機等在控制設備的時候，上海工業(yè)安燈看板什么價格，通電錢應該首先檢查一下連接線和控制板是否有無松動現(xiàn)象，不能隨便改動通訊線、扁平連接線的位置以及長度，上海工業(yè)安燈看板什么價格。 </p> <p> 三、軟件操作使用注意事項 · 定期檢查***，刪除無關的數(shù)據(jù) </p> <p> <br /> </p> <p> <br /> </p><div

</p> <p> （2）LED點陣模塊由若干晶片構成發(fā)光矩陣，用環(huán)氧樹脂封裝于塑料殼內。適合行列掃描驅動。 </p> <p> （3）貼片式LED發(fā)光燈（或稱SMD LED）就是LED發(fā)光燈的貼焊形式的封裝，可用于戶內全彩色顯示屏，可實現(xiàn)單點維護。 </p> <p> <br /> </p> <p> LED芯片藍光成分比較高，會對視網(wǎng)膜造成較大的影響。國家標準要求，普通照明LED產(chǎn)品需保證藍光危害為無危害級別或者低危害級別。尤其為小朋友選擇LED照明產(chǎn)品時，比較好選擇標注無危害級別的產(chǎn)品。這些信息可以在產(chǎn)品包裝上查到，消費者購買時應重視。 </p> <p> <br /> </p><div

屏體和屏體與建筑的結合部分必須嚴格的防水防漏；并且屏體要有良好的排水措施，一旦發(fā)生百了積水可以順利排放。 </p> <p> <br /> </p> <p> 在顯示屏及建筑物上需要安裝避雷裝置。顯示屏主體和外殼保持良好接地，接地電阻一般應≤4Ω ，這樣可以使雷電引起的大電流及時泄放。 </p> <p> <br /> </p> <p> 要做好屏體的內部的通風散熱措施，內部環(huán)境的溫度保持在負10度到40度之間。 </p> <p> <br /> </p> <p> 選用工作溫度在-40℃～80℃之間的工業(yè)級集成電路芯片，避免出現(xiàn)由于溫度過低導度致顯示屏啟動不了的情況。 </p> <p> <br /> </p> <p> 選擇高發(fā)光亮度的LED燈管，可以讓我們在陽光直射的情況下，仍然顯示效果良好，而且還可增強與周圍環(huán)境的對比，讓畫面的受眾更加寬廣。 </p> <p> <br /> </p> <p> <br /> </p> <p> 2、顯示屏結構安裝前檢查事項： </p> <p> <br /> </p> <p> 檢查底層的結構是否牢固。 </p> <p> <br /> </p> <p> 檢查結構的寬度和高版度是否達到標準，一般要比顯示屏尺寸大20mm-50mm為宜。 </p> <p> <br /> </p> <p> 檢查方筒和方筒之間的距離是否準確，否則屏體在安裝時會產(chǎn)生縫隙，嚴重時到上層很難安裝或者安裝不上造成返工權。 </p> <p> <br /> </p> <p> 檢查結構里面的通道位置是否合適，會不會擋住箱體的后蓋門。 </p> <p> <br />
